Patented Mar. 21, 1911.

To all whom "(It may concern:

Be it known that I, RICHARD B. ARMEN- TROUT, a citizen of the United States, residing at'Menardville, in the county of Menardand State of Texas, have invented new and useful Improvements in Compounds for Destroying Boll-Weevil, of which the follow ing is a specification.

This invention is an improved compound for destroying boll weevil, a pest-which is very injurious to cotton.

My improved compound consists of the following named ingredients in the proportion specified:

Sulfur .7 pounds Pine tar #4 pounds Asafetida A pounds Pulverized bluestone 1 pound Beaumont oil; 1 gallon Extract of tobacco 1 gallon A thick adhesive-0H1--- 5 gallons The mixture or compound is applied to the cotton plants while the same are being cultivated and is very destructive to the boll If the boll weevil has been particularly injurious during previous years the old stalks and the ground-should also be sprayed with dilute caustic alkali of the strength of about 10 pounds of the lye to 10 gallons of water. y

The tobacco extract. and Beaumont oil, which is a specific petroleum oil possessing slight insecticidal properties, serve as a vehicle for the solid constituents, which, when combined, form an emulsion which may be conveniently sprayed or spread over the Sun faces of the plant, but is not sufficiently adhesive in character to adhere strongly to the plant, and, hence, is liable to be washed off by rains.

which, in addition to preventing the emulsion from drying out and scaling ofi, waterproofs the mixture and causes it to adhere to the surfaces ofthe plant. Such adhesive oil, which is a compound oil, is referably composed of petroleum, third ii'action, 90 per cent., and fish oil, 10 per cent. This oil in addition to possessing the roperties mentioned, does not, like crude hydrocarbon or To overcome this objection, thethick adhesive oil referred to 1s employed,-

heavy greases, coat the composition sothickly as to decrease the efficiency of the inv secticide.

What is claimed is: A compound for destroying boll weevil comprising sulfur, pine tar, asafetida, blue stone, Beaumont oil, tobacco extract, and a lubricating oil.

In testimony whereof I afiix my signature in presence of two witnesses.

RICHARD B. ARMENTROUT.
